Abstract

The ATF2 project aims at demonstrating the strong vertical electron beam focusing capability, down to the few tens of nanometers level, of a down scale prototype of the final focus system of the next generation of e+e- machines. ATF2 offers opportunities to check in a real accelerator environment case for the performances of the beam transport and background generation code, used in the simulation of the future e+e- machines, BDSIM, and for the performances of its underneath particle-matter simulation code, Geant4.
